T0 allie/1.0m t may concer/1t:

Be it known that I, nvnr. E. Swami, a citizen of the United States, residing at Osage, in the county of Osage and State of Oklahoma, have invented certain new and useful Improvements in Machines for Truing Standing-Valve Packing-Rings,of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to machines for turning down or of truing new leather' rings when repairing. standing valves or oil well pumping rings.

The lower standing valve in an oil well pumping outfit is provided with a large numher of leather packing rings. lVhen these rings are new they are larger than the linterior diameter ofthe working barrel of the pump, andas a consequence the standing valve cannot be driven into place in the working barrel until the packing rings have been trimmed down to a tight driving t.

(lne object of my 'invention is to provide a simple and eiective machine for trimming down these packing rings after they are put in place. upon the standing valve, and for so trimming them that the exterior edges of the packing rings shall be truly concentric to the axis of the standing valve, and so that the exterior' faces of the packing rings will he even and smooth without either flat places or pro-tuherances.v

A further object of the invention is the provision of a machine of this character which may he. driven by han i if desired, and which is adapted to receive valves of any length. i

Still another object is to )rovide a knife support coacting with the chiicksl supporting the 'alve, this knife support heilig so ar.

ranged thatI the knife may he -adjusted both diametrically with relationlto theaxis ofirom said axis,

the valve and toward and y provide means and still another object is to for supporting the knife which willbrace4 the knife against lateral strain.

further object is to provide means which will causo the knife to move uniformly along the entire extent of the packinv rings, and in this connection to provide for readily placing the knife against the packing rings or removing it therefrom.

tlther objects will appeal' in the course of the following description.

' sleeve, as shown in Fig. 3, lacing provir i My invention is illust-rated in the accom .trui panying drawings, wherein- Figure l is a side elevation ot a. machine made 1n accordance `with my ,invent-ion; Fig. 2`1s a section on the line 2--2 of if Fig. 3 is a sectional view of the sleeve wiic f "tl sirpports the upper end of the knife carrier; Pig 4 1s a top plan view of the knife carry mg bar; Fig. 5 is av front elevation of j knife bar brace; Fig. 6 is a sectional view on the line GfG'of Fig. 2; Fig. 7 is a. secn tional view on the line 7-7 of Fig. l; .Tf f 8 is a sectional view on the line 82:8, Fin.

Referring to these figures, it will he si that `the frame of my machine consis" of the standards or posts 2 and 2 which are f'ii vertically disposed and spaced from each other. Each standard is reduced at itsion r end as at 3 so as to pass thro-ugh tahie other supporting bocht. A, and this reduced. lower end is screw threaded for engagement it with a nut 4. The upper end of each stan ard is connected hy means of iongiti nally extending har 5, the ends which reduced and pass -through the upper ends oit the standards and are engaged hy mits The lower ends of the standards are 'b1-"fc i from each other by means of a iongitn( bar 7. also reduced at its ends and h placeby nuts 8.

Mounted upon the upper har 2 for sliding er' movement the-realong is a sleeve 9., l

tri l with a projecting perforated ing l@ :tor gagement with the supporting menthe@ which will be later described'. f

Rotatably mounted upon thes'tanda and extending between the same shaft 1i formed with tL e screw one end of the feed shaft e through one of the posts 2 and vided with a detachable crank '13 a gear wheel 14. Slidably niomi the bars 5 and 7 for iongitudinal n'iovc i thereon is a cross head l5 which has an o ing'l through it. through which the 11 passes, this opening heilig of such titl ameter that the feed screw i2 does not gage with the wall of the opening.. ilfionnted upon this cross head t5 in manner which will he later described a chnc and engaged with this chuck and the cross -head 15 is an adjnstm i8. The rear end this through and has a bearing in the post 2, and mounted upon the end of this shaft is the crank 1S), this shaft 18 havin@ a collar 2G which bears a gainst the inner ilace ot' the 5, posts 2a.

Rotatably mounted in the stainlard or post 2 is a spindle 21 oi a driving chuck 22, and mounted upon this spindle is the spur gear wheel :22:3 which engages with the gear wheel l@ 11i and is driven thereby. These chucks 17 and 22 are interiorly conical in form so as to receive the opposite ends of a standing valve which .is illustrated in dotted lines in Fig. 1, and is designated'ft, the chucks bel ing' a l'ipioximateiy conical lfor the purpose of engr W ng standing4 valves having,V dilllerent diauueters. Yifhe chuck 2Q is provided with a diagonally arranged set screw 25 Vwhich is adapted to engage the openings of the QQ valve cage so as to hold the v ive 2st from reta lon relative to the chucl.

l-livolally ino ruled 'upon t lug 10 by means olvl the bolt or pivot pin 2G are the knife ff;in u m rl.iig members il?, ril'iere are two oi these members, spaceil from each other a (.leiinite distance, and each of the rfienibcrs is curved outward from the pivot point and then downward, as shown clearly in Fig. 2, these members being spaced from. 3a each otherl their entire length.,V ljisposed between the lower ends oit the knife supporting members 2? .s a bar Q8 pivoted to said members by ,means of a-ryet or bolt 29, this bar being formed with a recess .35 in its l'ace adapted to Iest upon and have sliding contact 'with the bar 22 and thus fnaort the kniie siuiporting; members 27 in definite spaced relation tothe bar 7,

"the guide bar S33 which extends beyond 40 the bar "a", as shown in Fig, Q, is -provided with aliandle 31 whereby the knife holder may be ia'nanipulated. rihe members 2f( are longitiulinally slotted at for the passage of an adjusting; bolt 33, the face of the meinbe2-s 2 being recessed as at 31 for the reception of a washer. )Disposed between the members 27 is a knife bar fili'. This knife bar slotted as l 9,/ op :ii-1. at L nus .slot oo inten secti n .gg 'Sing libe the base o' disposed at right z 55, The base of the knife is held to the scat by ineens et setbolt a0, shown clearly in i? The 'unite bar 35 is prolonged be "'lotted portion 3G to form a handle it may be easily manipulated. l between the upper ends a knife imr brace', illus "M 5, tbn brace being; upper end or `ne brace 1 l '.f., tnis base being l to form a tongue probetween the .in-embers 62?', and pwlegs of the brace by means of the rivet or pivot pin 46.

It will now be obvious that the knife bar may be oscillated upon the pivot 4G to raise or lower the knife and change its angle of inclination, and that the'knit'e may be held 75 in any angular adjusted position by 'tightening up upon the bolt It will also be seen that the knife bar may be adjusted toward or it'roni the axial center ot the chucks 17 and E22 by means of the bolt 33. The lower '80 end of the brace member 42 embraces the guide bar and thus the upper and lower ends of this brace member are held from lateral nioven'xcnt, and thus the knife bar is thoroughly braced 'from any lateral moveg5 nient.

rlhe lniiie earriage formed by the me-1nbers 2T, and 'l1-2 is automatically moved along 'frame oi" the machine or fed by et' the feed lever i? which is pivoted 9g ineai at its outer end between the members 27 by nieans et the rivet or pivot pin 4S. r1`he under tare of the feed lever a7 is formed with a screw threaded recess 4S) engaging with the screw threads 12 ot' the shaft 11 95 and the lever is held in engagement withthese screw threads by means of a coiled spring disposed in a socket in the lug, 10 and bearing against the upper face of the le'erlif?. The lever 47 is prolonged to form a. handle 51 whereby it may be manipulated. 1t is necessary that the chuck 17 should have swiveled engagement with the `Lross head 15, and to this end 1 form the member 1.7' at its y(base with a. central opening` 52 through which msses a collar 53, this collar vbeing;v to aned i ith a head 54 which bears against yhe inside face of the chuck 17. The cross'head 'l5 has an opening 55 just enough to receive the collarr 53, and the coilar is held in non-1otative engagement with the cross head by means ot' a set screw 55.` The interior of the collar is screw threided for engagement with the screw 's an the feed shaft 18, and it will be noted that this feed shaft has free movement through the collar and through the chuck.

The operation 0I" my invention is as follows: ln order to repair a valve and replace the oid rings with new, the cage is unserewed 'from the valve body, then the series of leather rings are placed upon the valve' body until. there are suiiicient rings on the1 body to make sure that the cage whe-n- 135 screwed down on the valve body w'ilklol1 the valves tightly .in place. The valve body and cage are then placed in the machine between the two centers or chucks 17 and moana/e body in the chuck 22, and the crank 19 is turned until the chuck bottom of the valve and crowds the valve to the center of both of the chucks, so that when the valve is turned it will, turn true, and the feed lever Je? of the valve carriage is then raised and the carriage is slid to the right until its knife moves to its starting point, that is` to the edge of the leather ringv next 'to the cage. rThe knife is then adjusted by the, raising' and'lowering or moving in and out the knife har 35 to suit the size ot' the valve 'to he operated on. lllhen the` knife has been adjusted to the right position the locking` nut' or bolt 33 tightened, and when the knife has been adjusted the lever l? is lowered down onto the screw l2 so that the threads on the lever 1:7 and', the `screw l2 are in mesh, then the crank 'i3 is turned and the carriage with the knife will move toward the lett, the knite trnnn'nng oli' the leather rings as it `goes. (it course the rotation ot' the crank lil will not only feed the knife but will rotate the valve body and its rings. After the knife has reached the other end ot' the valve.y then the 'feed lever -l-T is lifted and the carriage may be slid back to its starting` point and is thus readv tor another valve.

All stainling valves have a central opening #.YXtei'uling through the bottom ot the central opening; re-

vaive body, and this ceives the screw 1S in case this screw projects hevond 'the chuck 17. Thus when a loner val'fe is in the machine the chuck 1T and the cross head l5 are moved toward the d oi" the machine and the screw 18 will intend on through the chuckl and the valve. Oi' course the valve docs not touch the screw '18. and thus the centering' chuck turns with the valve when the machine is in motion.

lt will he seen that the knife may be readil'v removed for grinding or to permit the addition oi a new knife,.and it will also be seen that the knife is readily adjusted to secure the proper cutting angle and the proper depth of cut. The machine may casilv taken apart 'for transportation and ma;y be as eas-iig,7 set upn l have 'found it very eilective in actual practice. and that it not only cuts the valve leathers perfectly true, but that it does ver)T quicklyY work which heretofore has heen donc by hand and relatively7 slowly and with diiiicul,. =f.

lt will of course be ol ions that manjf minor changes might be made in the con-- struction oi' this device without departing,n irom the principle of the invention, and l therefore do not wish to be limited to the details "of constructirm as illustrated.
